About
This study examines the impact of nirsevimab, a new antibody, on reducing RSV-related hospitalizations in Luxembourg during the 2023/24 season. After its introduction, neonatal coverage reached 84%, leading to fewer hospital admissions for infants under six months compared to 2022. The average age of hospitalized children increased, and their hospital stays were shorter. Most severe cases involved non-immunized children. Nirsevimab's effectiveness aligns with clinical trials showing it reduces RSV severity in infants. The study highlights its potential benefits but notes limitations like short observation time and lack of outpatient data monitoring.
